These observations document past conditions at a small and variable scale. They are not to be confused with an avalanche forecast. They come from a variety of sources. We can only vouch for the quality of those produced by the SAC forecasters and professional observers.

Snowpack Observation 		Mt. Judah
Donner Summit Area 		Thin rain crust with 4-6mm surface hoar on top. Wind scoured slopes in the sun had soft supportable snow conditions Lower elevation solar aspects were punchy with wet surface snow The surface rain crust was breakable in mid elevation shaded aspects Tree drippings have created refrozen sections below canopy Looking south along the Sierra Crest towards Mt Anderson Forecaster

Snowpack Observation 		Tragedy Springs
Carson Pass Area 		Moderate signs of wind effect and loading within this area. Thick Ice crust from the recent rain event Monday. 40cm of boot penetration around 8200'. Rain runnels throughout the landscape. Snowboard turns did not produce roller balls on solar softened slopes. Falling debris from warming throughout the day on this small feature. Angulated crystals forming on surface of ice crust in shaded areas. Professional Observer

Snowpack Observation 		Mt. Judah
Donner Summit Area 		A cloud got stuck on Judah making it hard to see the larger avalanche paths. Ice coated all of the trees all the way to the summit of Mt. Judah at 8200 ft. ECTN on a wind-loaded test slope. Rain crust on the summit of Mt. Judah A thin rain crust existed at all elevations. Settlement cracks around trees showing consolidation in the new snow. Forecaster
